(54)	A reset driver circuit disposed on the same substrate as the image sensor

(57) A charge-coupled device for forming an electronic representation of an image from incident light, the charge-coupled device includes a substrate of a first type; a photosensitive area of a second type disposed in the substrate for receiving the incident light which is converted to a charge packet; a transfer mechanism for activating transfer of the charge packet through the charge-coupled device; an output mechanism for receiving the transferred charge packet; a reset operator for resetting the output mechanism to a charge voltage; and a logical element disposed on the substrate that inputs a gate waveform to the reset operator for activating the resetting operation of the reset operator.
